Wheat starch diet: suitable for patients with chronic renal failure. Dietary characteristics: 1. Patients with chronic renal failure cannot excrete nitrogen metabolites normally, so they need to restrict dietary protein intake, but in order to improve the patient’s protein nutritional status, moderate amounts of milk and eggs are selected within the total protein intake allowed. Lean meat type of high quality protein. 2.Replace some or most of the staple foods with wheat starch and reduce the intake of rice and noodles, so that the total protein intake can be controlled within the range that the renal function of patients with chronic renal failure can bear, in order to both reduce the renal load and improve the protein malnutrition. 3. Determine the protein intake according to the degree of kidney function damage, and generally determine the total protein intake (mostly 20-40g/day) by the endogenous creatinine clearance, blood urea nitrogen and blood creatinine test results. 4. Give high carbohydrate and moderate fat to supply the required caloric energy. 5.Do not use all stimulating foods and condiments, and limit sodium salt if you have water retention, and limit potassium salt if you have no urine and little urine. 6.Wheat starch can be made into pastry, steamed dumplings, noodles, cookies, batter and various cakes.
